One of the most beautiful settings for a bar I have seen in Spain. It is really wonderful the combination of architecture, colors and traditional Spanish objects.
It is a must if you are in Mallorca, it is a bit more expensive then the rest of the bars in La Lontja (the area where is located) and Palma, but it is definitely worth it.
But come on, if you were able to afford a trip to the Balearic Islands, you can always afford the 16€ per cocktail.
The place is priceless. I highly recommend it.
